Physics in Slashdot

• Where do high energy gamma rays crashing into the Earth come from? These guys say they come from the supermassive black hole at the center of our galaxy.
  
  
• A somewhat silly article about how Hollywood handles the laws of physics.
  
  
• What to do about a shortage of science and math teachers? The answer to all problems apparently is money. Speaking of which, there are places in this country where I would make more as a high school science teacher than I do now (well, base salary that is).
  
  On a completely unrelated note, I'm in a good mood because of the Libby verdict yesterday. Nice to see the system work occasionally. I really hope history gets it right and that this period is rightly remembered as pure adulteration of what our country stands for.
